Knitting is an intricate process by which consecutive loops or stitches are formed to turn yarn into fabrics. The needle and sinker which form the frictional partners in a circular knitting machine are exposed to severe stresses and demand special lubricating film.

  • The lubricating oils should be able to form a strong thin film to endure the high speed movement of the needle and sinker as well as to ensure extended life of the friction partners.
  • The oil needs to operate under varying friction zone and coefficients’ of friction and provide consistent performance over extended periods.
  • Considering the operating condition, the oils should have fluff rejection tendency.
  • The oil should not form any residue due to gradual increase in temperatures that could in turn hamper the speed sliding movement.
  • The oil should be able to retail an uniform film on the frictional surfaces grind intermittent machine usage. it should have good oxidation stability to ensure minimal wear during machine startup.
  • The oil should easily pump through the pulse meter. Also, it should not react with the plastic tubes or machine paint, even when in contact for extended period of time.
  • Oils stains on fabric during regular operation is a distincet possibility. However these stains should be easily washable and not impact the dyeing process.

Applications and Properties

The unique pictograms help identify primary characteristics of the lubricant as well as key applications and industries it has been established at a glance. However the final recommendation would still have to be by the BECHEM specialist after having studied application and its operating environment. As the saying goes, ‘every problem has a unique solution, if only, one is looking for it’. This is the core philosophy to our approach towards ‘Application Engineering’ and staying true to ‘speciality’

Frequently Asked Questions

Short bytes for queries on lubricants that always bothered you

Greases are made by mixing a solid material, called a thickener, with a base oil and property enhancing additives; but it’s the oil that forms the lubrication film. For better understanding, grease thickener can be thought of as a sponge saturated with oil. Moving parts squeeze the oil out of the sponge like thickener for forming the lubrication film. Typically, the base oil constitutes the largest proportion of grease weight at about 80-90%, followed by thickener at 10 to 20% and additives under 10%.

Dropping point of a lubricating grease is an indicator of the heat resistance of the grease. and is the temperature at which the grease is no more a thickened lubricating medium. The dropping point indicates the upper temperature limit at which a grease retains its structure, not the maximum temperature at which a grease may be used.

The most important feature of a grease is its consistency.  A grease that is too stiff may not get pumped into areas requiring lubrication.  While a grease that is too fluid may leak out. Grease consistency depends on the type and amount of thickener used and the viscosity of its base oil.  A grease consistency is its resistance to deformation by an applied force.

The measure of consistency is called penetration.  Penetration depends on whether the consistency has been altered by working.  Standard test procedures established by American Society for Testing and Materials International (ASTM) and accepted by industry are ASTM D 217 and D 1403,  measure penetration of unworked and worked greases.

The NLGI has established consistency numbers ranging from 000 to 6, corresponding to specified ranges of penetration distance of the standard cone into the test grease.  Table below lists the NLGI grease classifications along with a description of the consistency of each classification.

Viscosity: It is a measure of resistance to flow of a lubricating oil.

Viscosity index: It is defined as rate of change of viscosity with respect to temperature.


  • It is the most important property which determines the performance of lubricating oils under the influence of temperature
  • A lubricating oil should have sufficient viscosity to retain a lubricating film on the surface
  • On machine part moving at slow speeds under high pressures, a high viscous oil should be used as it better resists being squeezed out from between the rubbing parts.  Light oils can be used for lower pressures and high speeds.
  • It is not possible to maintain a liquid oil film between two moving or sliding surfaces if the viscosity is too low and hence excessive wear will occur.

The pour point of an oil is the minimum temperature at which the oil turns into semi solid and almost losses its flow characteristic. At low temperatures, the viscosity of the oil will be very high, causing the oil to resist flow. This is important in equipment that operates in a cold environment or handles cold fluids.
